Is there a greater chance for infections in the genital area if you are pireced down there???

Most infections of the vagina are yeast related, an I have never heard of an anal infection unless you were doing something very wrong. There is a chance of you getting an infection of the wound, especially if you introduce it to the sweat and fluids of sex before it's entirely healed or put it under stress that re-opens the wound.

If you do get an infection on the wound, there is VERY little chance that it could spread to the vagina or anus, because it's a different kind of 'infection.'

I think there is a risk compared to non pierced people. This is because those with piercings have the ability to damage them, get them snagged, and injure themselves. This injury could cause an infection if not treated and cared for. However, this is independent of the normal happenings of genitals, like Ryuson said.

So you have a higher risk for injury and potential infection, but if you're careful, you're fine. Your most fragile time is when you first get the piercing. You have to refrain from most forms of sexy time and keep the area cleaned. The good news is that these piercings heal very quickly due to the high levels of blood flow.
